I want to put a stainless or chrome thermostat housing on my L03 to match the Performer Intake and Chrome Valve Covers. Problem is, I can't find one! All the ones I see say "Late Chevy" and have that real long bolt thread on its right side instead of the two short ones the stock has. Anyone know where I can find a stainless or chrome thermo housing for the L03? Also some new stainless bolts?

You could always take your stock one and polish it. Proform makes a bunch but I haven't found a late model one yet. You may want to check out their site. I will move this so you can get some ore opinions. i am sure their is something out there.

Just get a "Late Chevy" housing and it will work with the LO3.

I have one on my engne, just a chrome one i bought at checker, works fine.

*EDIT*

Here is a picture.

Where did you get the bolts to fit the housing?

The Mr. Gasket Chrome one will work fine for you. I got mine at Advance.
